The main contrast covering both structure and reproduction between a virus and a microbe is the point. Viruses are tiny living objects, consisting of either DNA or RNA inside a system of protein structures that provide it with protection. In order for viruses to duplicate, their genetic material must be inserted within a host cell, and consequently, the host cell machinery has to be overrun to manufacture the viral particles. In contrast, bacteria can live independently, since they are single-celled living organisms which have an own metabolism and, as per requirement, can reproduce without being a host cell. Bacteria assume a more complicated morphology, such as cell wall and nucleoid, have a great ability to survive independently of the host organism. Viruses and bacteria are the two main agents of the diseases and their operations of entering the body and multiplication mechanism are in a great contrast
